“Windows Update” text using strange characters

Question

I'm seeing strange characters used to render the words "Windows Update". View the screenshots below to see what I mean.

Is this a known 'easter egg' from devs or is something else going on?

Model: Lumia 640 XL LTE

OS build: 10.0.15223.0

Language: English (United Kingdom)

Answer 1

These looks like "pseudo localised" text - i.e. it's practically in English, but uses non-latin characters to check that character encoding issues haven't been introduced, and that everything that should be localised is (i.e. it's obviously wrong, but the QA staff can identify the meaning, rather than just seeing a blank label).

This is a common practice used by different software houses, and it looks like in this case the translation was missed in that specific insider build.
